WARNING: Handling the cord on this product or cords

associated with accessories sold with this product, will

expose you to lead, a chemical known to the State of

California to cause cancer and birth defects or other

reproductive harm.

Wash hands after handling.

BASIC BATTERY LOAD TEST

(Conventional & Maintenance-Free Types)

1. Connect clamps to battery posts Red (+) Pos, Black

(-) Neg and note the battery’s capacity. Engine and all

electrical accessories must be off when testing battery.

2. Hold load switch “on” for 10 seconds.

3. Read meter with load still on then refer to battery

analysis table on back of Tester.

COLD TEMPERATURE EFFECTS

A battery will test lower when cold than when warm. For

more accurate results, please reduce the battery’s nominal

rating by 200 cranking amperes (one step on meter scale)

for each 20°F drop below 40°F. If cranking ampere rating is

800 and battery temperature is 0°F, test as a 400 cranking

ampere battery (i.e. 2 steps down).

Battery capacity is OK. Battery may or

may not be fully charged. Check spe-

cific gravity of battery to determine state

of charge, check for electrical drain or

possible charging system trouble. Re-

charge battery to full level.

Battery capacity is not satisfactory. Bat-

tery may be either defective or not fully

charged. Check specific gravity to de-

termine which condition exists. If charg-

ing does not bring specific gravity to full

charge level, battery should be replaced.

Battery may be defective or very run

down. Release load switch and note volt

meter reaction. Voltage recovery to 12

volt or above within seconds indicates

defective battery. Slow voltage recovery

indicates run down condition. For best

results, check specific gravity.

STARTER MOTOR TEST

1. Connect clamps to battery posts and do the basic

battery test. In addition, note the exact voltage with the

load test on. If voltage continues to fall after 10 seconds,

this test cannot be preformed.

2. Apply the voltage obtained above to starter test table

on the scale plate. In this case, please use the next

higher minimum cranking volts for the engine of less

than 200 CID. For example, if load voltage is 11.00,

use 10.2 for minimum cranking voltage.

STARTER TEST

3. Disable the ignition system without starting, crank the

engine and note the voltage.

4. If cranking voltage of Step 3 is below the minimum

cranking voltage in starter test table, the starter current

draw is excessive. If starter cranks slowly, check for

high resistance or poor connections.

CHARGING SYSTEM TEST

1. Connect clamps to battery for basic load test.

2. Operate engine at fast idle.

3. Note meter reading with all electrical accessories off.

It should be in green “good” band in “charging system”

scale.

4. With headlights and blower motor on high, meter

should remain in green “good” band.

5. If meter reads red band or outside the charging system

zone, trouble is indicated.

NOTE

On initial use of your Battery Tester, smoke may

develop. This is caused by the lubrication burning off

the heater coils. This will not affect the performance of

your Battery Tester and will diminish upon further use.
